Ability to use one udp port for multiple wg interfaces

[Jason A. Donenfeld]

Hello Damian,

1. Always use the latest snapshot version of WireGuard. The one you
listed is out of date.

2. No, you cannot use the same port.

3. You may have multiple peers on a single wireguard interface. This
is the configuration that you probably should be using. "It is not
very friendly to open additional udp ports in multiple peer scenario
where firewall ACLs are desirable" This is 100% incorrect. With
multiple peers on an interface and a sufficiently clamped allowed-ips
entry for each, you'll have perfect firewall ACLs.

Regards,
Jason
